[BUG] Missing author parameter on repositories()->commits()

[mjadsmurai]

As documentation states, there's an author parameter:
https://docs.gitlab.com/ee/api/commits.html

But this SDK is missing it:
https://github.com/GitLabPHP/Client/blob/11.11/src/Api/Repositories.php#L203

When i try to use it, it throws an exception saying that author doesn't exist.

$client->repositories()->commits($projectId, [
    "author" => "demo@demo.com"
]);

DIrect curl requests against /repositories/commits with author parameter do work, so it's just missing in this sdk definition :o

Fixed in 11.12.0
